Ultraphor prevents yellowing of light-colored textiles
Leading chemical company BASF has developed the textile auxiliary Ultraphor AUX-NY.
Sold! In selecting a new shirt or T-shirt, that first impression is everything. White garments should be brilliant white; pastel-colored fabrics should look fresh. To thwart clothing from yellowing during transport and storage, BASF has developed the textile auxiliary Ultraphor AUX-NY.
Many manufacturers produce garments in countries far from the markets where they are sold. Before shirts and T-shirts end up on department store shelves, they have to cover thousands of kilometers.
The long period of transport and storage packed in film can cause areas of yellowish discoloration on light-colored clothing.
Known as storage yellowing, such areas occur especially at points where the film and fabric are in permanent contact. Colorless BHT – an additive in the packaging material – migrates onto the garment and reacts with nitrogen oxides from vehicle exhausts, producing a yellow nitro dye. The phenomenon is promoted by moisture and high temperatures.
The new BASF product Ultraphor AUX-NY prevents nitrogen oxides from combining with the BHT molecule, so that yellowing cannot occur and the textile retains its light shade. Seconds and returns due to yellowish discoloration become a thing of the past.
Ultraphor AUX-NY can be applied to all textiles, both white and pastel-colored. It is silicone-free and does not stain. Since the auxiliary does not foam in the production process, no additional silicone antifoams are needed. Textile manufacturers therefore benefit from problem-free fabric processing.
